It's understood the couple decided to go their separate ways towards the end of last year, with Scott, who often travelled to watch his Serbian-born lady love compete while in Australia, nowhere to be seen during her Hopman Cup campaign in Perth last week.

A rep for Scott declined to comment on the break-up but a source close to the couple confirmed what has been a persistent rumour in tennis circles for several weeks.

"They are both constantly travelling ... it was just a matter of geography in the end, really," the insider told Confidential.

It's not the first time Scott and Ivanovic have split, with the couple breaking up midway through 2010 before rekindling their romance.
